Lifestyle and diet may stop or reverse prostate cancer progression

Men with early stage prostate cancer who make intensive changes in diet and lifestyle may stop or perhaps even reverse the progression of their illness, according to a new study. more  

Ethanol treatment may be instrumental in fighting IV-based infections

Inserted through the skin and into a vein, long-term intravascular devices such as IV catheters deliver to patients a range of life-saving medications, nutrition and fluids, among other uses. more

Sticky mutant proteins implicated in Lou Gehrig's disease

A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell. more  

Promising therapies for hemophilia & heart disease

Hemophilia is a hereditary blood disease, primarily affecting males, where the blood fails to clot causing potentially life-threatening 'bleeds'. About one in 6000 Australian males is born with hemophilia in severe, moderate or mild form. People with hemophilia rely on intravenous infusion of recombinant Factor VIII clotting protein. more

Researchers discover new tumor defense system  

Researchers have discovered that tumors release fatty acids that interfere with the cells that are trying to kill them. Consequently, strategies that reduce the amount of fatty acids surrounding the tumors may give a boost to anti-cancer therapeutics. The details of these findings appear in the September issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal. more

First large-scale evaluation of iris recognition under way  

The National Institute of Standards and Technology (NIST) has announced that it is running the Iris Challenge Evaluation (ICE), the first large-scale evaluation of iris recognition. more

Chemical link indicated between drinking and certain cancers

Researchers at the National Institute of Standards and Technology (NIST) have developed a new chemical analysis method that has assisted researchers at the National Institute of Alcohol Abuse and Alcoholism (NIAAA), National Institutes of Health, in demonstrating a potentially important chemical link between alcohol consumption and cancer. Using this novel chemical assay, they have uncovered a chain of chemical reactions that, under physiological conditions, may lead from alcohol to a known mutagen. more
